META CONTAINER.

Application filed May 19, 1925. Serial No. 31,305.

wall of the container to secure a permanent joint between the bung ring and the metal of the container wall. Heretofore great difliculty has been experi'- enced in positioning bung rings and providing between them and the container walls permanent joints or connections which would prevent the ring from getting loose due to the repeated screwing in and unscrewing of the bung plugs, with resulting leakages. To insure a permanent joint of this character as well as one that was liquid tight, different means and methods have been employed and resorted to, all necessitating extra expense and labor.

One object of my invention is to construct an improved bung ring and to provide an improved method and means-for. securing the ring in position in the opening therefor in the'container wall in such manner that the ring will be interlocked with the metal and thus be'permanently held in position in fixed parent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanyin drawings, whereinig. 1 is a fragmentary side elevation of a container embodying my invention, parts being broken away. 4

Fig. 2 is a fragmentary section of the container before the bung ring is positioned in the opening therefor.

Fig. 3 is a plan view of the parts shown in 4 Fig. 1.

Fig. 4 is a section on the line 4-4 of Fig. 3. Fig. 5 is a section on the line 55 of Fig. 3. Fig. 6 is a plan view of a bung ring embodying my invention and adapted for use in struction. 5 indicates an opening formed in connection with my process of interlocking the ring with the metal of the container wall. F g. 7 s a section on the line 77 of Fig. GI F g. 8 s a section on-the line 8-8 of Fig. 6, Fig. 1s a side view of the ring, being taken on the line 9-9 of Fig. 6 looking in the direc tion of the arrows.

. In the drawing, 1 indicates a container whlch may be formed in any suitable manner from sheet metalstock. The container comprises a body 2 and a head 3, the flanges of these parts being seamed in any desired manner. For illustrative purposes, I have shown a container 1 having a head 2 that is fiangeless or chimeless with a seam tbetween the flanges ofthe body and head of the'contamer, this construction of container formmg the subject matter of my co-pending appllcat on Serial N 0. 42,982, for which reason no claim is made herein to' said container conone wall of the container, for example in the head 3. 6 indicates a bung ring ada ted to be positioned in theopening 5 according to the method hereinafter sctforth. 6 indicates screw threads on the inner wall of 7 the ring to provide means to removably secure the plug (not shown) in the ring. The ring 6 is preferably drop forged, but may be of any other form of construction. If desired, in forming or shaping the ring 6, I provide-it with a body portion 7, to form a relatively wide seating base 7, and a neck 9 As shown, the side wall of the bod port on 7 is provided with a plurality of so stantlally fiat sides or faces 8, disposed at angles to each other. The neck 9 is adapted to project through the opening 5, which is made to exactly fit the neck 9, with the metal of the wall surrounding the opening in engagement with the seating base 7 of the body portion. 90 The neck 9 extends beyond the wall of the opening 5 to provide sufficient metal to permit it to be riveted over upon the wall of the head to secure the ring thereto. My inventionconsists in providing means for interlocking themetalof the bung ring 6 and the metal of the wall 3 surrounding the 0 eniug 5 so that danger of the ring getting oose due to positioning of the plug (not shown) and removal thereof, is entirely overcome. These interlocking means comprise what may be termed lands 1.0 disposed upon the seating upon. -While the lands may be of any de- 10 metal of the wall being compressed by this sired height, I prefer to make them of less height than the thickness of the Wall 3, the purpose being to cause them to project into ,the metal of the wall against which the seat-.

ing" base 7 'fits without causing, a bulging of the wall 3 on its opposite surface, the

action so that an interlocking relation will re.: 'sultbetween the wall and ring. This form of construction not only permits the rings to be readily and economically manufacturedbut also permits the riveting to be effected, in a single operation by simple tools in an ordinary manner. By preference, the body;

portion of the ring is, arranged on the'inner" surface of the head 3 and'its neck projects through the opening 5 to the outside of the free end of the neck is riveted over upon the upper surface of the head 3. In the manufacture of the rings I prefer to incline the seating base'Z downwardly at an angle, toward the axis of the ring, from the side faces 8 thereof ;.thereby providing what may be termed a conical'base or surface 7*. As a result of this form of construction, the lands 10 are provided at-the corners formed by the angle faces 8, since these. points of the body portion are at a greater distance from the axis of the ring than the intermediate portions of the side faces. The rings may bedropforged with the seating base 7 inclined in the manner shown, or they may be otherwise made with flat seating basesfand then the bases may be machined to the desired angle.

In forming the opening 5', Iprefer to bend the wall surrounding the opening downwardly, as shown in Fig. 2, so that the wall will. fit against the seating base 7 a when the neck 9 of the bung ring 6 isfitte'd into the opening. 5; this arrangement also facilitates the riveting of the neck" into its-final position with the metal gripped between the seating I base 7 a and riveted portion of the neck. As

shown in'fFig. 5, the lands 10 are pressed. into the metal of the wall 3 and the latter is clamped against the seating base at all points between the lands, due to the pressure applied in riveting the neck 9 overv into final position, thus becoming interlocked therewith, as clearly shown in Figs. 1, 4 and 5. In my construction, the lands 10 are uniformly spaced around the ring and being uniformly projected into the metal they act to prevent turning'of the ring when a force is applied in arotative direction to turn the plug. In my form of construction the lands 10 neck, sai

are formed simultaneously with the forging of. the ring and the interlocking relation ber tween the, lands 10 and wall of the head 3 is effected in connection. with the riveting of the,

neck of the ring over on the metal. It will therefore be seen that iii-providing the 1ntel-locking means described and interlocking the ring dWalIB together no extracost v or labor'is involved. Itwill also be noted that my construction and method provide for without resort to welding or manipulation of the wall 3 and that one operation only isv .75? the permanent positioning of" the bung ring e To those skilled in the art to-wh ich my in and widely differing embodiments and applications of the invention will suggest them-' selves without departing from the spirit scope thereof. My disclosures and the description herein'are' purely illustrative and are not intended to be in any sense limiting. Whit I claimis: 1. A bung ring: comprising a neck and a body portion forming a seating base and having'flat side walls disposed at angles to each other and a land on said seatin base at each corner formed by said side w s. i

'2. A bung ring comprising a body ortion forming a'seating base. and havin' at side walls dis osed at angles'to each ot er and a seating base being inclined downwardly to provide lands at the corners of said side walls.

the opening and a neck riveted over into engagement with the other face of the wall, said 4 lands being of less height than the thickness of said wall and adapted to be compressed into the metal thereof; when the pressure for riveting is-applied to said neck.

4.. .A metal containerhaving an opening formed in its wallin'combination with a bungringmounted in said opening, said ring vention relates many changes in construction comprising a body portion having aseating base fitting against one face, of the wallsuroverinto' engagement with the other face of thewall, said body portion having fiat side faces lands which are. compressed'into the rounding the opening and a neck rivetedwardly, to leave at the corners of said side metal of the wall when pressure for riveting the neck is applied thereto:

5. A bung ring comprising a body portion having flat side walls disposed in angular relation and a neck, the upper face of the 3. A metal container having an opening weasel 3 I booiy portion around the neck'being of frustoat angles to each other anti laniis on saii conical shape circumferentially, whereby seating base at certain of the corners formlfl iands are formed on said upper face at the by said side walls, m
